Paper Abstract

Fiber optic amplifier is a field of new growing interest owing to its application to the optical metro and access networks for amplifying a weak optical signal. In order to design short-fiber-length and broadband optical amplifier, a new amplified fiber with semiconductor inner cladding has been presented. The semiconductor optical amplifier (SOA) is usually pumped by electric currents, but an optical pump is used to the semiconductor inner cladding fiber amplifier in our work. The rate equation is derived in the optical pumped amplifier, and the properties of the amplifier are analyzed. Comparison with conventional optical pumped amplifier, the semiconductor inner cladding fiber amplifier can be pumped by a wide-band optical pumped power, and high pump efficiency can be designed.
